IMPROIIEMEN '1' IN HARVESTER-RAKES.

The 'Schedifle referred to in these Letters Patent and making part of the same To all whom it maycom'ern: Be it .known that I, WILLIAM F. Gounnrne, of

the city and county of Providence, and State of Rhode Island, have invented a certain new and useful Harvester-Rake.

My invention relates wholly to certain novel'combina 'tions of mechanical devices for producing an even and regular upward and downward movement of harvestcr- I rakes, and is applicable only to that class of machines which may be provided with single rakes, mounted in a rake-head, supported upon sliding bars, or their parts of my 'inveution, the same being mounted upon a'small' platform for the purposes of illustration.

A represents the sliding bar or traverse rail, upon "which the carriage and rake-head is mounted. This "bar is square by choice,.and is firmly attached at each end to suitable standards.

B is the carriage, mounted upon the slide-bar A, which passes through the carriage longitudinally, and to whichit is well adjusted. l

- 0 is the rake-head, to which the rake is attached.

1) is a spindle, onwhich the rake-head is mounted,

between two projecting ears of the carriage. One' of its ends projects some distance beyond the ears of the carriage for a p'ilrpose hereafter explained.

, E is one of three pintles, entering the but of the rake-head on a radiating line with the center of the spindle D, and at right angles to it.

F is a horizontal swinging lever, attached by a pivot to and underneath the carriage B.

G is one of three curved grooves in the upper side 'of the outer end of the lever. These grooves are fitted with relation to the piutlesE on the rake-head O, in such a manner that the movement of the lever to the right or left, causes, by t 1e cam efi'ect of the grooves upon the piutles, a vertica rising or falling of the rake,

the outer eud of the rake describingthe arc of a cir- V ole, of which the spindle D would be the center.

H and H are stop-blocks, firmly placed at proper distances apart, at or near each end of the slide-bar A. Their oflice is, by resistance to the lever]? while the carriageB is still moving, to cause the raising or lowering of the rake.

I is a spiral spring,-embracing the protruding end of the spindle D. The outer end of this spring is sooured to the end of the spindle, while its other end engages with the carriage B. It is all so arranged thatthe spring shall counterbalance the weight of the swinging rake, nd secure for it at all times an even Figure 2 represents, in vertical cross-section the same as in' fig. 1, and more clearly exhibits the lever B and its connection with the pintles E. The various parts are lettered as in fig. 1.

Figure 3represents in perspective upon a larger scale, the lever F with its groove s'G.

Figure 4. represents a portion of a harvester platform, and illustrates a mode of application of my invention.

L is the platform.

The slide-bar A is at right .angles to the cutter-bar.

M is the driving-shaft, fi'om which power is com municated to thecarriage by means of an endless chain, which passes over a grooved pulley on the end of the shaft, and also over a loose grooved pulley on a studnear the cutter-bar. p

To this chain a reciprocating motion is imparted by' a proper movement of the shaft M, to which power may be applied in an obvious manner.

,Parts are lettered in this as in the other'figures. The operation of my invention is as follows: p The rake being at its farthest point from the cutterbar and raised to a vertical position, advances toward the cutters upon the slide bar A, moved by the endless chain attached to the carriage. Just before its arrival. at the point nearest the cutter-bar, the lever B engages with the stop-block H which throws the rake from a vertical to a holizoutal position and in contact with the fallen grain.

As the machine progresses, the chain, by its backward or. reciprocating movement, conveys the carriage and rake, with the grain on the platform, back to the point of delivery, and just before arriving at the end of the .barA, the lever F engages with the stop-block H, which causes the rake to again assume a vertical position, ready for repeating the motions already described.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent 1. In combination with the sliding bar A and carriage B, the swinging lever F, provided with .camgrooves, engaging with pintles in the but of the rakehead, and operated by contact with the stop-blocks H, substantially as described, for the purposes specified.

and described.
